   Single source of truth for how SetLight looks. Every page links this file.
   Colours sampled from the logo (docs/SETLIGHT_BRAND_SYSTEM.md, 2026-08-03).
   This is SetLight's OWN brand — never the artist brand Brand/Wordmark Studio
   generate for customers. Do not put customer palettes in here.
